Specification of Letters Patent.

Patented May 9, 191%.

'. To all whom it may com-cm:

Be it known that l, Wiurrnnn S. Eocene, a citizen of the United State residing at Bantam, H1 the county of Litchtleld and State of Connecticut have invented certain new and useful Improvements tainers, of which the following 3 ec1l1- cation, reference being had to the ucconr panying drawings.

This invention rel tes to an. improved cage-or retainer for hearing" halls.

'he principal objects of the ii vent-ion are to provide a construction -for this purpose whichcan be formed oi two simple pieces of sheet metal adapted to be stamped out and formed in similar dies; to provide a construction of this character in which the two parts of the retainer can be brought together and permanently united to each other by machinery before the balls are applied; to provide means whereby although these parts are rigidly held together yet their edges are separate irom'each other so that the ballscan. be forced between them into their positionsin the perforations without danger of disconnecting or dislocating the parts; and toprovid'e exceedingly simple means whereby in as mlohng they must necessarily be assenihled'in exactly the right position with respeotto each other, said means also constituting means for prevent ing thetwo parts turning on each other and thus getting cutoil register and permitting the balls to bind,

For a full. understanding of the invention, reference is to he had to the following description and accompanying drawing, in whicht Figure l is a transverse sectional view of av ball retainer or cage constructed in accordance with my invention; Fig. 2 is a. similar view with the parts unattached and arranged in juxtaposition to each other; and 3 is a fragmentary oircum'ierential section.

Qorresponding and like parts are referred to in the following description and designated in all of the views of the accompanying drawing lay like reference characters.

Referring to the drawing, the numerals 1 and 2 designate two complemented annular olates or sections that desigi'ied to mate one with the other, each being provided with any desired number of openlugs 3 for the bearing balls 4. Due of the said plates is formeu with a centrally disposed annular flange 5 and the other plate is correspondingly formed with a centrally disposed annular liunge (3, which fits snugly within the flange 5, as clearly illustrated in the drawing. The flange 6 in its initial con dition is straight or plane, transversely considered, and in the manufacture of the cage or retainer, the relatively free edge oi said flange is pressed by a suitable die or the like outwardly in a radial direction into close contact with the adjoining slightly rounded attached or base end of the flange 5.and flush with the outermost face of the adjoining plate, whereby the two plates 1 and 2 will be held together without soldering, welding or independent fastening devices and both side laces'of the cage or retainer will. be unitorm.

il/leans is provided whereby the loall receiving openings 3 of the plates 1 and 2'shall be held in absolutely true transverse alinement or registry with each other, and t0 efiect this result, 1 form in each of the flanges 5 and 6 transversely disposed notches or grooves designated 8 and 9 respectively, grooves being punched" or otherwise formed in the manufacture of the plates in the metal of which the flanges are formed and producing slight ribs or protuberances on the peripheries of the flanges. The groove 8 the flange 5 extends through the same, being open both ends and throughout its extent, as clearly illustrated in the drawing, whilst-he groove 9 terminates at and is closed in the relatively free edge of the 6 which is subsequently pressed outwardly to form the bead 10,. It will at once he seen that by the provision of these registering grooves or notches, no mistake can he made in assembling the parts and hence the hall receiving openings 8 of one plate will he to 'be in true alinement or registry with the corresponding openings of the other plat-e. Moreover, the two parts can be assembled in aminimum of time on account of the fact that the notches 8 and 9 are arranged longitudinally with respect to the direction in which the parts are put together. This reduces the cost of manufac tux-e because the assembling is an important element of that cost. Moreover, when assembled notches absolutely prevent the two 5 cm turning on each other the perforations out 1 if}: I Being .of registration, therefore the balls will not bind in practice. The permanent' uniting of the two elements of the retainer by means of the bead 10 is also an important feature perforated annular plates provided on then because in this way a solid double Wall is secured at the inner side of the annulus which gives the article great strength at this point although formed of "cry thin sheet metal. Yet thetwo plates project freely from the edges of this annulus and after the other parts are assembled the balls can be inserted from the edges by forcing them in, springing the plates apart by that act and allowing the plates to spring back into position again or forcing them back into place. On account of the strong and positive connection of the two plates at the center there is no danger of their becoming disconnected or dislocated when the balls are forced into position between them" This avoids the necessity of placing the balls around on one plate and then securing the other plate in position while those balls are in a condition from which they can easily be dislodged. In other words the two plates are not assembled while the balls are held simply by one plate as has been necessary in some previous cases.

Although I have illustrated and described only a single embodiment of the lnventlon,

. I am aware of the fact that many modific:

tions can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be Copies of this patent may be obtained for limited to all the details of construction herein shown and described, but

What I do claimv is V 1. A ball retainer comprising a pair 01:

mner peripheries with integral cylindrical flanges adapted to fit in close telescopic en- -gagement, means for rigidly securing said pair of telescopically engaged cylindrical flanges together With their ends in firm engagement about the inner peripheries 0t said perforated annular plates, and interengaging means projecting from the outer peripheries of said cylindrical flanges for positioning and positively locking said flanges against relative turning.

A. ball retainer comprising a pair of perforated annular plates provided on their inner peripheries. with integral cylindrical flanges adapted to fit in close telescopic engagement, positioning and locking ribs extending axially on the outer peripheries of said cylindrical flanges and adapted to interengage in the telescopic engagement of said flanges. and means for rigidly securing said pair of telescopically engaged cylindrical flanges together with their ends in firm engagement about the inner peripheries of perfive cents each, by addressing the "Commissioner of Patents.
